Benefits of technology

0015] With pollution on the increase, there is a need to find other agents for effectively combating the harmful effect of pollutants on keratin materials and to prevent the adhesion of these pollutants on keratin materials, and in particular to avoid the degradation of cell respiration, the desquamation and accelerated ageing of keratin materials and especially the skin, and also to combat the dull complexion and the early formation

Problems solved by technology

Urban environments are regularly subjected to peaks of pollution.
These elements may react with the oxidizing agents and become impaired, which will promote the desquamation phenomena.
Thus, the harmful effects of pollution on keratin materials affect cell respiration of these keratin materials and are reflected by accelerated ageing of the

[0092] Phase A (fatty)

2 Phase A (fatty): Monodiglyceryl stearate 3 g Liquid petroleum jelly 3 g Cetyl alcohol 5 g Phase B (aqueous phase): Polyethylene glycol oxyethylenated with 3 g 50 mol of ethylene oxide Water qs 100 g Phase C Extract of maize (Phytovityl .RTM.) 5 g Water l0 g

[0093] Procedure

[0094] The fatty phase (A) and the aqueous phase (B) are prepared separately and heated to 70.degree. C. The fatty phase is poured into the aqueous phase with stirring. The emulsification is continued for 10 minutes and the mixture is then cooled slowly with stirring to a temperature of 40.degree. C. Phase C is added and the cooling is continued. A cream that can be applied to the skin to protect it against the effects of pollution is obtained.

Abstract

The present application relates to the use in topical application of at least one gramineous extract as an anti-pollution agent, and especially as an anti-pollution cosmetic agent. The application also relates to a cosmetic treatment process for protecting the body against the effects of pollution, in particular against the effects of heavy metals, by applying to keratin materials a composition containing, in a physiologically acceptable medium, an effective amount of at least one gramineous extract.

Description

[0001] 1. FIELD OF THE INVENTION[0002] The present application relates to the use, for example in topical application, of at least one gramineous plant extract as an anti-pollution agent, and to a cosmetic treatment process for protecting the keratin materials against the effects of pollution, in particular against the effects of heavy metals, which comprises the application to keratin materials of a composition containing, in a physiologically acceptable medium, at least one aqueous, alcoholic or aqueous-alcoholic gramineous extract.[0003] 2. DISCUSSION OF THE BACKGROUND[0004] Urban environments are regularly subjected to peaks of pollution. An individual in his daily environment, and particularly in an urban zone, may be subjected to a whole range of factors attacking keratin materials, and in particular the skin, the scalp and the hair, by various airborne pollutants. Atmospheric pollutants which are represented largely by the primary and secondary products of combustion represen...
